Simple Screen Particle Effect

I want to use Particle Effect to have my game a little bit of design in the background.
Here’s an example:

The default of the Particle Effect is only in cone and I don’t have idea on how the parameters of it works so I hope someone can help me out for the right set of parameter that will result of having the whole screen have a Particle Effect.

It is necessary to spend a lot of time to find the correct parameters. I suggest you to test the gdevelop examples games to find a settings solution similar to your needs.

Those floating particle in Dungeon Dash are not from a particle emitter. They’re randomly moving single object sprites. You’ll have to program them yourself.
